CARDINGMACHINE.

forming part of Letters Patent N0. 321,331, dated June 30, 1885.

Application filed November 2S, 1883. (No model.) Patented in England May 15, 1883, No. 2,432; in France November 20, 18.*"3, No. 1583373; in Belgium December 27, 1883, No. 63,671, and in Germany January 1l, 1884, No. 28,029.

`and ELrJin Asnwonrn, subjects ofthe Queen of Great Britain and Ireland, and residing at Manchester, county of Lancaster, England, have invented an Improvement in Carding- Machines, (for which we obtained a. patent in Great Britain, No. 2,482, dated May l5, 1883,) of which the following is a specification.

Our invention consists of certain improvements in the construction of cardingmachines, in which the main cylinder is provided with end plates or disks to assist in producing a fleece of brous material with straight and regular edges, as fully described and claimed hereinafter.

In the accompanying drawings, Figure l is an end view of a carding-engine cylinder with our invention applied thereto. Fig. 2 is a sectional view of one end of the cylinder with the removable disk applied thereto. Figs. 3 and 4 are detached views, on a larger scale, of the appliances for fixing the disk or ring when it has been detached from the cylinder. Fig. 5 is a diagram illustrating the position of the disk or ring during the grinding ofthe cylinder-clothing.

In Fig. 2, a is one end of the main cylinder of a cardingengine. Z) is the central shaft or axle, and c is the disk or ring which we apply to the cylinder. The en d of the cylinder is turned true, and the disk cis secured to the cylinder end by means of screws d. The disk is, by preference, made of sheet-steel. The card-clothing extends right up to this disk, and the lickcr-in, the doffer, and the dats or rollers just enter between the peripheries of the two disks,which project a littlc beyond the wires of the clothing at the ends of the cylinder, so that the whole of the width between these disks is evenly covered with cotton, which is carded right up tothe disks. The two disks thus limit the width of the carding-surface, and prevent the cotton 5o f, which is formed with a head, f, which can notch, it.

pass through the enlarged end of the slot c. In this head is turned a groove about equal in width to the thickness of the disk. The Screw is provided with a conveniently-shaped tapped handle, g, or with an ordinary nut, or with any suitably-shaped nut or screw handle. When the head of the screw is entered into the circular hole at one end of the slot e, and is pushed sidewise along the slot, the holder is secured to the disk by the edges of the slot passing into the groove in the head ofthe bolt. This being done in the case of both slots in both the disks, the screws d are removed, the disks being then sustained by the resting of the holders upon brackets 7L 71., which are secured to the ordinary framing, i, of the earding-engine. In each bracket 7i is formed a Wrhen the two holders are moved sidewise, the part of the screw between the head f and the boss of the handle y drops into this notch, as indicated in Fig. 4., and the two handles are turned, so as to tighten up the screws. The disk is then iirmly held in a position eccentric with relation to the axis of the cylinder, as shown at Fig. 5, and the tightening of the screws has withdrawn the disks a little 'from the cylinder, so that the latter can run clear of the disk on each side. The wires of the card-clothing will now project at one part beyond the peripheries of the disk, as indicated in Fig. 5, and a grinding-roller can be applied to grind the carding-surfacc. The disk c may have a larger hole in the center than the proportion as indicated in the drawings, sc as to be more in the nature of aring, and instead of being a complete disk or ring, as indicated, it may be applied in separate segments.

lVe are aware of the construction proposed in British Patent No. 2,519, of 1862, to prevent the fibrous material from passing sidewise77 from the cardingrylinder; but in thatv case the rings are ,xedly applied to the peripheries of the cylinders, are of the same diameter as the clothed cylinder, and are ground away when the cylinders require sharpening.7

XVe claim as our invention* 1. The combination of the cylinder and the frame of a @aiding-engine, havingi support-ine- IOO ing the grinding of the carding-snrface, substantially as set forth.

In testimony whereof We have signed our names to this specification in the presence of 15 two subscribing Witnesses.
